Abstract

Provided is a packaging cooler box for delivery, comprising a bottom portion to form a lower surface upon conversion into a box mode, a plurality of sidewall portions configured to connect with the bottom portion, a lid portion configured to connect with one of the sidewall portions, and to face said bottom portion upon conversion into the box mode, a crease portion formed along the edge of the bottom portion so that the sidewall portions can stand upright, joint portions configured to join said sidewall portions, to be folded to face itself and to be in close contact with the sidewall portions, upon conversion into the box mode, and easy adhesive portions provided in said joint portions and sidewall portions to maintain the box shape upon conversion into the box mode from a single plane consisting of said bottom portion, sidewall portions, said lid portion and joint portions.

First claim

What is claimed is:

1. A packaging cooler box for delivery, comprising:
a bottom portion to form a lower surface upon conversion into a box mode;
a plurality of sidewall portions configured to connect with the bottom portion;
a lid portion configured to connect with one of the sidewall portions, and to face said bottom portion upon conversion into the box mode;
joint portions configured to join said sidewall portions, to be folded to face itself and to be in close contact with the sidewall portions, upon conversion into the box mode; and
easy adhesive portions provided in said joint portions and sidewall portions to maintain the box shape upon conversion into the box mode, each of the easy adhesive portions configured for repeated attachment to and detachment from another one of the easy adhesive portions,
wherein said bottom portion, sidewall portions, said lid portion and joint portions constitute a single plane in the unfolding mode, provided that said bottom portion, sidewall portions and joint portions form a single rectangular shape to avoid jamming when introduced into a cleaning device, and
wherein said joint portions are configured to come into contact with the inside of the sidewall portions standing upright in the box mode.

2. The packaging cooler box of claim 1 , wherein
said joint portions each have a rounded corner.

3. The packaging cooler box of claim 1 , wherein
said easy adhesive portions are formed symmetrically on the joint portions so that, while each of the joint portions is folded, the two opposing faces thereof can be bonded together.

4. The packaging cooler box of claim 3 , wherein
said easy adhesive portions are formed on said joint portions along the sides which are adjacent to the sidewall portions.

5. The packaging cooler box of claim 4 , wherein
said easy adhesive portions are formed along the edge of said joint portions.
